      "value": "An issue was discovered on Renesas SmartBond DA14691, DA14695, DA14697, and DA14699 devices. The Nonce used for on-the-fly decryption of flash images is stored in an unsigned header, allowing its value to be modified without invalidating the signature used for secureboot image verification. Because the encryption engine for on-the-fly decryption uses AES in CTR mode without authentication, an attacker-modified Nonce can result in execution of arbitrary code."

      "value": "Se descubri\u00f3 un problema en los dispositivos Renesas SmartBond DA14691, DA14695, DA14697 y DA14699. El Nonce utilizado para el descifrado sobre la marcha de im\u00e1genes flash se almacena en un encabezado sin firmar, lo que permite modificar su valor sin invalidar la firma utilizada para la verificaci\u00f3n de im\u00e1genes de arranque seguro. Debido a que el motor de cifrado para el descifrado sobre la marcha utiliza AES en modo CTR sin autenticaci\u00f3n, un Nonce modificado por un atacante puede provocar la ejecuci\u00f3n de c\u00f3digo arbitrario."
